+Summary: Error loading/manipulating images with Mono
+
+I have some code which uses the System.Drawing.Image classes to load image 
+files, perform some manipulations, and then output the results to a HTTP 
+response stream via an ASPX page..  The code works fine on a windows 
+system running the MS.NET runtime.  When I run the code on a debian box 
+running xsp / mono 1.1, it generates errors.
+
+Steps to reproduce the problem:
+1. Extract the files from the attached zip file into a web accessible 
+directory
+2. Request one of the varios test files through xsp.
+3. A image should be returned
+
+Actual Results:
+
+An error similar to this is returned..
+
+System.ArgumentException: Invalid Parameter. A null reference or invalid 
+value was found.

+
+Expected Results:
+
+A manipulate image should be returned.
+
+How often does this happen? 
+
+Consistently, I have 4 individual test files which all work on the ms 
+runtime but fail using mono / xsp.
+
+Additional Information:
+
+Linux 2.4.27-2-386
+Debian Sid / Testing
+
+The following are the debs installed on the system..  These packages are 
+from the unstable / Sid distributions..  They are a little mixed because 
+debian doesn't have a "stable" release of mono yet.  I don't know if this 
+contributes to the issue?
